A nurse is preparing to administer magnesium sulfate 1 g in 100 mL of 0.9% sodium chloride over 2 hours. The drop factor of the manual IV tubing is 30 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver?

Step 1: Identify the formula for manual IV drip rate gtt/min = (Volume (mL) × Drop factor (gtt/mL)) ÷ Time (min) Step 2: Identify values Volume = 100 mL Drop factor = 30 gtt/mL Time = 2 hours = 120 minutes Step 3: Plug in the values gtt/min = (100 × 30) ÷ 120 = 3000 ÷ 120 = 25 gtt/min
